Description

Technical Field

[0001] The present application relates to the technical field of gas equipment, and in particular to a gas stove and an energy-gathering pot rack thereof. Background Art

[0002] When the gas stove is working, the gas enters the stove from the air inlet pipe, enters the burner after being adjusted by the gas valve, and is mixed with a part of the air (this part of the air is called primary air). The mixed gas is ejected from the fire hole of the ignition distributor and ignited by the ignition device to form a flame (the air required for combustion is called secondary air). The flame is used to heat the cookware placed on the energy-gathering pot rack.

[0003] The air required for the primary air replenishment of the gas stove in the related art comes from the bottom of the cabinet, so the cabinet is required to have ventilation holes to replenish air from the outside to the cabinet. However, in the case where the cabinet does not have ventilation holes, the burner of the gas stove is usually set as an upper air inlet burner, that is, the part of the burner above the stove panel has ventilation slots, and the secondary air is replenished through the ventilation slots, while the soup can be blocked from flowing into the gas stove. In addition, ventilation holes are formed through the bottom wall of the burner, and the air outside the burner enters the bottom shell through the ventilation points and ventilation holes in turn, and is used as primary air to replenish the injection pipe. However, in order to enhance the energy gathering effect, some products on the market currently have seamless contact between the bottom of the energy gathering pot rack and the upper surface of the stove panel, which will affect the replenishment of primary and secondary air, resulting in incomplete combustion and cabinet explosion defects.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] As described in the background technology, in the prior art, when the cabinet is not provided with ventilation holes and is used for a long time, problems such as incomplete combustion and cabinet explosion still occur. The inventor has found through research that the reason for this problem is that the energy-gathering pot rack arranged on the outside of the stove head is closely spaced from the stove head, and there are no ventilation holes on the energy-gathering pot rack, and there is no gap contact with the stove panel. The energy-gathering pot rack will hinder the ambient air from entering the ventilation groove, that is, the amount of air entering the bottom shell is small. Therefore, when the cabinet is not provided with ventilation holes and is used for a long time, it is easy to cause incomplete combustion and cabinet explosion due to insufficient primary air supply.

[0037] Based on the above reasons, the present application provides a technical solution for an energy-gathering pot rack and a gas stove that can make combustion more complete and improve safety.

[0038] See also Figures 1 to 5 , Figure 1 The structure diagram of an energy-gathering pot rack according to an embodiment of the present application is shown. Figure 2 The exploded structure diagram of a gas stove according to an embodiment of the present application is shown. Figure 3 Shows Figure 2 Enlarged structural diagram at A. Figure 4 Shows Figure 2 Cross-sectional structural diagram of the structure shown. Figure 5The structure diagram of a gas stove of an embodiment of the present application is shown. An energy-gathering pot rack 10 of a gas stove provided in an embodiment of the present application is used to be arranged on a stove panel 20 and circumferentially arranged around a burner 30. The energy-gathering pot rack 10 is provided with an air guide channel 101 extending from the outer circumference of the energy-gathering pot rack 10 to the inner circumference of the energy-gathering pot rack 10. At least one air guide channel 101 is used to be arranged opposite to and communicated with a ventilation slot 3101 on the burner 30.

[0039] The energy-gathering pot rack 10 of the gas stove is provided with at least one air guide channel 101 extending from the outer circumference to the inner circumference. Thus, when the energy-gathering pot rack 10 is arranged around the outer circumference of the burner head 30, the external air can be connected with the ventilation slot 3101 on the burner head 30 through the air guide channel 101, so that the air can enter the ventilation slot 3101 through the air guide channel 101, so that on the one hand, it can flow to the position near the fire cover of the burner head 30 as secondary air to supply the burner head 30, and on the other hand, it can enter the interior of the bottom shell 40 as primary air and flow to the air inlet 36 of the ejector tube to supply the burner head 30, thereby making the flame burn more fully, improving the combustion efficiency, and solving the problems of incomplete combustion, flashback, yellow flame, high carbon monoxide concentration, etc. caused by insufficient oxygen supplementation during operation of the gas stove. In this way, even if the cabinet is in a completely closed state, primary air is supplied, so that various defects such as incomplete combustion, flashback, yellow flame, high carbon monoxide concentration, etc. can be effectively avoided.

[0040] The number of air guide channels 101 on the energy-gathering pot rack 10 is more than one, for example, two, three, four, five, six or more. Since there are multiple air guide channels 101 on the energy-gathering pot rack 10, more air supply can be achieved. In addition, when the energy-gathering pot rack 10 is rotated and adjusted on the stove panel 20, at least one air guide channel 101 can be positioned opposite to and connected to the ventilation slot 3101 on the stove head 30, that is, the energy-gathering pot rack 10 can be rotated at will, and the assembly operation on the stove panel 20 will also be more flexible.

[0041] In some embodiments, the outer contour of the energy-gathering pot rack 10 includes, but is not limited to, regular shapes such as circles, ellipses, polygons, and other irregular shapes, which can be flexibly adjusted and set according to actual needs, and are not limited here. In addition, the radial cross-section of the energy-gathering pot rack 10 includes, but is not limited to, polygons, circles, ellipses, etc., which can be flexibly adjusted and set according to actual needs, and are not limited here. For example, polygons are rectangles, pentagons, hexagons, etc.

[0042] Among them, when the gas stove is working, as the oxygen around the fire cover of the burner 30 is gradually consumed, a negative pressure area is formed, and the area around the energy-gathering pot rack 10 is a positive pressure area due to sufficient oxygen, which can realize the flow of air from the positive pressure area to the negative pressure area, that is, the air flows to the fire cover of the burner 30 through the air guide channel 101 and the ventilation slot 3101, so as to realize the secondary air supply around the fire cover. The specific shape of the air guide channel 101 in this embodiment can be flexibly adjusted and set according to actual needs, for example, it can be set to a Venturi channel, a straight channel, a curved channel, etc. Among them, the curved channel can be a broken line channel, an arc channel, or a combination of a broken line channel and an arc channel. In addition, the shapes and sizes of each section of the air guide channel 101 along its extension direction can be kept consistent, can be gradually changed, can be a sudden change, etc., and can be set according to actual needs.

[0043] See also Figure 1 , Figures 3 to 5 In one embodiment, the energy-gathering pot stand 10 includes a main body 11 and at least one air inlet pipe 12 penetrating the main body 11. Each air guide channel 101 is formed in each air inlet pipe 12. The air inlet pipe 12 includes at least one or a combination of a venturi tube, a straight tube or a curved tube. Thus, when the air inlet pipe 12 is set as a venturi tube, compared with a straight tube or a curved tube, the speed of air supply to the burner 30 can be greatly increased, thereby increasing the air supply amount, which is conducive to more complete combustion.

[0044] Specifically, a plurality of venturi tubes are arranged along the circumferential direction of the energy-gathering pot rack 10, and each venturi tube is evenly arranged. The specific number and the distance between two adjacent venturi tubes can be flexibly adjusted and set according to the shape of the energy-gathering pot rack 10. Among them, the venturi tube includes a contraction section 121 and a diffusion section 122 connected to the contraction section 121. The contraction section 121 and the diffusion section 122 are arranged in sequence along the airflow direction. The air flow is guided from the positive pressure area to the contraction section 121. At the minimum diameter of the contraction section 121, the air flow velocity reaches the maximum, and then flows to the diffusion section 122 to reduce the air flow velocity, so that oxygen can be quickly and evenly provided to the burner 30 for combustion.

[0045] There are multiple air guide channels 101 and multiple air inlet pipes 12 . Each air guide channel 101 is formed in each air inlet pipe 12 .

[0046] See also Figure 1 , Figures 3 to 5 In one embodiment, each air guide channel 101 is arranged at equal intervals on the energy-gathering pot rack 10. In this way, it is beneficial to make the air supply of each part of the energy-gathering pot rack 10 in the circumferential direction more uniform, and the gas combustion can be more complete.

[0047] See also Figure 4 In one embodiment, the main body 11 includes but is not limited to a hollow annular structure. Thus, a heat-insulating space 102 is formed inside the main body 11 and is arranged circumferentially around the central axis thereof. When the energy-gathering pot rack 10 is sleeved on the burner 30 and is working, the heat-insulating space 102 forms a heat-insulating layer, which can effectively block the radiant heat generated by the gas stove during operation from being transferred outward, thereby increasing the combustion efficiency.

[0048] See also Figure 4 In one embodiment, the energy-gathering pot rack 10 includes an outer peripheral side wall 111, an inner peripheral side wall 112, and at least one supporting foot 13 for supporting the pot. The inner peripheral side wall 112 is spaced apart from the outer peripheral side wall 111, the outer peripheral surface of the energy-gathering pot rack 10 is located on the outer peripheral side wall 111, the inner peripheral surface of the energy-gathering pot rack 10 is located on the inner peripheral side wall 112, and the supporting foot 13 spans and connects the inner peripheral side wall 112 and the top surface of the outer peripheral side wall 111; the air outlet of the air guide channel 101 is located at the lower part of the inner peripheral side wall 112. Specifically, the energy-gathering pot rack 10 also includes a top wall 113 connecting the outer peripheral side wall 111 and the inner peripheral side wall 112. The outer peripheral side wall 111, the inner peripheral side wall 112, and the top wall 113 are in contact with the stove panel 20 and enclose to form a heat-insulating space 102. In this way, the energy-gathering pot rack 10 is configured in a shell shape, which can save material costs and reduce weight. At the same time, since the heat-insulating space 102 is formed in cooperation with the stove panel 20, it can play a role in heat preservation, thereby increasing combustion efficiency.

[0049] Specifically, the outer peripheral surface of the energy-gathering pot rack 10 is formed on the outer peripheral side wall 111, and the inner peripheral surface of the energy-gathering pot rack 10 is formed on the inner peripheral side wall 112. The "outer peripheral side wall 111 and the inner peripheral side wall 112" can be "a part of the top wall 113", that is, the "outer peripheral side wall 111 and the inner peripheral side wall 112" can be integrally formed with the "other parts of the top wall 113"; or they can be an independent component that can be separated from the "other parts of the top wall 113", that is, the "outer peripheral side wall 111 and the inner peripheral side wall 112" can be independently manufactured and then combined with the "other parts of the top wall 113" into a whole.

[0050] In addition, the opposite ends of the air inlet pipe 12 are respectively penetrated on the outer peripheral side wall 111 and the inner peripheral side wall 112. The "air inlet pipe 12" can be "a part of the outer peripheral side wall 111 and the inner peripheral side wall 112", that is, the "air inlet pipe 12" and "the other parts of the outer peripheral side wall 111 and the inner peripheral side wall 112" are integrally formed; or it can be an independent component that can be separated from "the other parts of the outer peripheral side wall 111 and the inner peripheral side wall 112", that is, the "air inlet pipe 12" can be independently manufactured and then combined with "the other parts of the outer peripheral side wall 111 and the inner peripheral side wall 112" into a whole.

[0051] In some embodiments, when a liquid pan 50 is provided on the stove panel 20, the inner peripheral side wall 112 is specifically, for example, abutted against the liquid pan 50, that is, indirectly abutted against the upper surface of the stove panel 20, and can also be enclosed with the outer peripheral side wall 111, the top wall 113 and the stove panel 20 to form an insulating space 102.

[0052] See also Figure 1 and Figure 5 In one embodiment, one or more supporting legs 13 are provided on the top surface of the energy-gathering pot rack 10, and the supporting legs 13 are used to support the pot body. Specifically, the supporting legs 13 are, for example, two, three, four or more in number, and each supporting leg 13 is arranged at intervals and abuts against the bottom surface of the pot body at the same time, which can not only stably support the pot body, but also form an air gap between the pot body and the top surface of the energy-gathering pot rack 10, so that air can smoothly enter the interior of the burner 30, so that the gas burns more fully.

[0053] See also Figures 1 to 5 In one embodiment, a gas stove includes the energy-gathering pot rack 10 of the gas stove of any of the above embodiments, and further includes: a bottom shell 40, a stove panel 20 and a burner head 30. The stove panel 20 is covered on the bottom shell 40, and an opening 21 is provided on the stove panel 20. The burner head 30 is inserted into the opening 21, and the burner head 30 includes an upper air inlet burner 31 extending to the outside of the bottom shell 40, a fire cover assembly provided on the upper air inlet burner 31, and an ejector pipe assembly located inside the bottom shell 40 and connected to the upper air inlet burner 31. A ventilation slot 3101 and a ventilation hole 3102 connected to the ventilation slot 3101 are formed on the upper air inlet burner 31. The ventilation slot 3101 is arranged opposite to and connected to the air guide channel 101, and the ventilation hole 3102 is connected to the bottom shell 40. The energy-gathering pot rack 10 is disposed on the stove panel 20 and is disposed around the circumference of the stove head 30, and an annular seamless contact is formed between the energy-gathering pot rack 10 and the upper surface of the stove panel 20. Specifically, the bottom of the outer peripheral side wall 111 of the energy-gathering pot rack 10 is in seamless contact with the upper surface of the stove panel 20. In other words, the bottom of the outer peripheral side wall 111 of the energy-gathering pot rack 10 is in seamless contact with the upper surface of the stove panel 20, so that the primary air or the secondary air cannot flow into the stove head 30 through the contact position between the bottom wall of the energy-gathering pot rack 10 and the upper surface of the stove panel 20.

[0054] The above-mentioned gas stove is provided with at least one air guide channel 101 extending from the outer circumference to the inner circumference. Thus, when the energy-gathering pot rack 10 is arranged around the outer circumference of the burner 30, the external air can be connected with the ventilation slot 3101 on the burner 30 through the air guide channel 101, so that the air can enter the ventilation slot 3101 through the air guide channel 101, so that on the one hand, it can flow to the position near the fire cover of the burner 30 as secondary air to supply the burner 30, and on the other hand, it can enter the interior of the bottom shell 40 as primary air and flow to the air inlet 36 of the ejector tube to supply the burner 30, thereby making the flame burn more fully, improving the combustion efficiency, and solving the problems of incomplete combustion, flashback, yellow flame, high carbon monoxide concentration, etc. caused by insufficient oxygen supplementation during operation of the gas stove. In this way, even if the cabinet is in a completely closed state, primary air is supplied, so that various defects such as incomplete combustion, flashback, yellow flame, high carbon monoxide concentration, etc. can be effectively avoided.

[0055] See also Figures 2 to 4 In one embodiment, the upper air inlet burner 31 includes a first air inlet structure 311 and a second air inlet structure 312 circumferentially arranged around the first air inlet structure 311. The fire cover assembly includes a central fire cover 32 arranged on the first air inlet structure 311 and an outer ring fire cover 33 arranged on the second air inlet structure 312. The ejector pipe assembly includes a first ejector pipe 34 connected to the first air inlet structure 311 and a second ejector pipe 35 connected to the second air inlet structure 312. The first air inlet structure 311 includes an outer ring support plate 3111, an inner ring support plate 3112 spaced apart from the outer ring support plate 3111, and a connecting portion 3113 connected to the outer ring support plate 3111 and the inner ring support plate 3112, respectively. The ventilation slot 3101 is formed on the outer ring support plate 3111, and the ventilation hole 3102 is formed on the connecting portion 3113.

[0056] See also Figure 3 and Figure 4 In one embodiment, the air outlet of the air guide channel 101 is located below the fire hole of the fire cover assembly. In this way, during combustion, negative pressure can be formed, and the wind from the outside of the energy-gathering pot rack 10 flows into the burner 30 through the air guide channel 101 to achieve the air guide effect.

[0057] See also Figure 3 and Figure 4 In one embodiment, at least one vent 3103 or a plurality of vents 3103 spaced apart along the circumferential direction of the inner ring support plate 3112 is provided through the inner ring support plate 3112. In this way, air can enter the vicinity of the center fire cover 32 through the vent 3103, so that air can be supplied to the center fire cover 32 as secondary air, so that the flame of the center fire cover 32 burns more fully, and can also enter the bottom shell 40 as primary air for supply.

[0058] In one embodiment, the ventilation slots 3101 are provided in a plurality and are arranged at intervals along the circumferential direction of the outer ring support plate 3111. In this way, it is advantageous for the air guide channel 101 to be aligned and connected with the ventilation slots 3101, so that air can enter the ventilation slots 3101 through the air guide channel 101, so that on one hand, it can flow to the position near the fire cover of the burner head 30 as secondary air to supply the burner head 30, and on the other hand, it can enter the interior of the bottom shell 40 as primary air and flow to the air inlet 36 of the ejector pipe to supply the burner head 30, thereby making the flame burn more fully and improving the combustion efficiency.

[0059] In one embodiment, a plurality of ventilation holes 3102 are provided and spaced apart along the circumferential direction of the connecting portion 3113. In this way, the air entering the ventilation slot 3101 can enter the interior of the bottom shell 40 through the ventilation holes 3102 as primary air, and flow to the air inlet 36 of the ejector pipe to be supplied to the burner head 30, thereby making the flame burn more fully and improving the combustion efficiency.

[0060] See also Figures 2 to 4 In some embodiments, the gas stove further includes a liquid pan 50 disposed on the stove panel 20. The liquid pan 50 is arranged at the opening 21 and is arranged circumferentially around the burner 30 to prevent liquid from entering the gas stove and causing damage to the device. In addition, the inner peripheral side wall 112 of the energy-gathering pot rack 10 abuts against the liquid pan 50, which plays a positioning role for the liquid pan 50 and the stove panel 20, preventing the liquid pan 50 from moving up and down, and preventing the stove panel 20 from moving up and down.

[0061] See also Figures 2 to 4 In some embodiments, the gas stove is further provided with various devices such as a pulse igniter 60, an ignition needle 70, a thermocouple 80, etc., so as to realize the ignition function.
